post vacation blues?

Don't know if I'm just sad that my time off is over or what. Im also agravated at my daughters for being so damned needy. Knocking on the bedroom door all the time, waiting for me to come feed them, cook for them buy them what they need...YOUR OVER 18 ALREADY GET A LIFE COOK FOR YOURSELVES FOR A CHANGE ERRRRGGGGGGGGGGGGGGGGGGGG  When can I just take care of myself my needs my desires I am selfish but I want to be selfish for a change. I'm sick of being there for everyone else but myself. WHy must I always come last?
